LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS#include<sys/types.h>intlfs_segwait(fsid_t*fsidp, structtimeval*tv);
DESCRIPTIONlfs_segwait() blocks until a new segment is acquired for writing by the
file system specified by *fsidp or if *fsidp is -1, until a segment is
acquired for writing by any LFS file system.
If timeout is non-zero, lfs_segwait() will return after timeout
milliseconds regardless of whether a new segment has been designated for
writing or not.
RETURNVALUESlfs_segwait() returns 0 if a new segment was acquired; 1 if it timed out;
or -1 on error.
ERRORS

[EFAULT] fsidp points outside the process's allocated address
space.
[EINTR] A signal was delivered before the time limit expired
and before a new segment was designated for writing.
[EINVAL] The specified time limit is negative.
